MIAMI (AP) — The Republican presidential candidates at Wednesday’s debate all say they support Israel, but they are squabbling over China and Ukraine. Donald Trump was again absent, holding his own event nearby. At center stage were Ron DeSantis and Nikki Haley, who are fighting for a distant second place in the Republican field. Both traded allegations that the other had welcomed Chinese investment into their state. Tim Scott, Chris Christie and Vivek Ramaswamy were also onstage. They face new urgency to cut into Trump’s margins with the leadoff Iowa caucuses just two months away.
